Hello, I am a newbie to ES and would appreciate any insights into the below issue (going crazy for the last couple of hours :/): I need to store the following string value into a field -- foo\bar -- with the literal backslash in it. curl -XPUT '[http://localhost:9200/test/test/test](http://localhost:9200/test/test/test)' -d ' { "rules": [ { "users" : ["foo\bar"] ] }' I get the following error: {"error":"RemoteTransportException[[High-Tech][inet[/X.X.X.X:9300]][index]]; nested: MapperParsingException[failed to parse [rules.users]]; nested: JsonParseException[Unrecognized character escape 'k' (code 107)\n at [Source: UNKNOWN; line: 10, column: 42]]; ","status":400} I tried "foo\bar" and the value gets stored as "foo\bar". Any ideas on how to store "foo\bar" with the literal backslash in it? Thanks in advance! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Thanks. I provided a bad example as I guess I over-simplified it and also edited it to remove proprietary data (thus, missed }). The following example exhibits the same issue as described in my original post. curl -XPUT '[http://localhost:9200/test/test/test](http://localhost:9200/test/test/test)' -d ' { "rules": [ { "users" : ["mile\kilo"] } ] }' {"error":"RemoteTransportException[[High-Tech][inet[/X.X.X.X:9300]][index]]; nested: MapperParsingException[failed to parse [rules.users]]; nested: JsonParseException[Unrecognized character escape 'k' (code 107)\n at [Source: UNKNOWN; line: 5, column: 40]]; ","status":400} On Thursday, September 18, 2014 2:02:12 AM UTC-4, vineeth mohan wrote: > Hello , > > This don't have to do anything with the escape character - > Try below - > > curl -XPUT '[http://localhost:9200/test/test/test](http://localhost:9200/test/test/test)' -d ' > { > "rules": [ > { > "users" : ["foo\bar"] > } > ] > }' > > Thanks > Vineeth > > On Thu, Sep 18, 2014 at 6:55 AM, Foobar Geez \<[fooba...@gmail.com](mailto:fooba...@gmail.com) > \\> wrote: > > > Hello, > > I am a newbie to ES and would appreciate any insights into the below > > issue (going crazy for the last couple of hours :/): > > > > I need to store the following string value into a field -- foo\bar -- > > with the literal backslash in it. > > > > curl -XPUT '[http://localhost:9200/test/test/test](http://localhost:9200/test/test/test)' -d ' > > { > > "rules": [ > > { > > "users" : ["foo\bar"] > > ] > > }' > > > > I get the following error: > > > > {"error":"RemoteTransportException[[High-Tech][inet[/X.X.X.X:9300]][index]]; > > nested: MapperParsingException[failed to parse [rules.users]]; nested: > > JsonParseException[Unrecognized character escape 'k' (code 107)\n at > > [Source: UNKNOWN; line: 10, column: 42]]; ","status":400} > > > > I tried "foo\bar" and the value gets stored as "foo\bar". > > > > Any ideas on how to store "foo\bar" with the literal backslash in it? > > > > Thanks in advance! > > > > -- > > You received this message because you are subscribed to the Google Groups > > "elasticsearch" group. > > To unsubscribe from this group and stop receiving emails from it, send an > > email to [elasticsearc...@googlegroups.com](mailto:elasticsearc...@googlegroups.com) \. > > To view this discussion on the web visit > > [https://groups.google.com/d/msgid/elasticsearch/1f4a3fb8-6835-4851-a354-acd5fa8f97bb%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/1f4a3fb8-6835-4851-a354-acd5fa8f97bb%40googlegroups.com) > > [https://groups.google.com/d/msgid/elasticsearch/1f4a3fb8-6835-4851-a354-acd5fa8f97bb%40googlegroups.com?utm\_medium=email&utm\_source=footer](https://groups.google.com/d/msgid/elasticsearch/1f4a3fb8-6835-4851-a354-acd5fa8f97bb%40googlegroups.com?utm_medium=email&utm_source=footer) > > . > > For more options, visit [https://groups.google.com/d/optout](https://groups.google.com/d/optout). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
